CTD20 Deep Cut Hole Saw 01175

This 25/32” (20mm) Carbide Tipped Deep Cut hole saw (CTD) is the perfect solution for repeated intensive drilling in mild and stainless steel, cast iron, aluminum and copper of all thicknesses up to and including 1” (25mm ). The CTD hole saw features three different angles ground on to the cutting face of each tooth on the saw. This 3-Ply tooth grind delivers a fast cut, minimal snag when the saw begins the cut, efficient swarf removal minimizing heat build up, and maximum saw life. CTD will power through sheet, stainless steel up to 1" (25mm) thickness, enclosures, pipework and structural steel work with either a fixed or portable drill, in a fraction of the time taken by a standard hole saw.

This hole saw cuts at least TWICE AS FAST as a standard hole saw, saving time and increasing productivity. Ideal for production environments!
